A significant degree of PFE develops rapidly in a majority of persons dying of blunt force trauma. Although the source of fat for embolization has been suggested to be bone marrow, no evidence of myeloid tissue was found in any of the lung sections. Nor was there a correlation of PFE and number of fractures. Soft tissue injury is considered the primary cause of PFE.

Nursing home residents comprise a large and rapidly growing segment of the national population. Despite this fact, the majority of deaths occurring in nursing homes are not investigated because of the significant medical illnesses suffered by most residents. Herein, we report a series of unnatural deaths in nursing home residents, including two homicides and seven accidental deaths. In four of the deaths, there was an attempted concealment of the cause and manner of death. Fearing criminal or civil proceedings, nursing home personnel may attempt to conceal homicidal or accidental deaths in nursing home residents. Because of the serious, chronic illnesses suffered by these patients, attending physicians are often willing to sign death certificates without personally investigating the circumstances surrounding the patient's demise. The authors contend that unnatural deaths of nursing home patients are significantly underreported. Attending physicians and death investigators should be urged to investigate more fully sudden deaths in nursing home patients.

Serious and fatal injuries can be sustained when anatomic structures are in close proximity to an airbag module cover at the moment of airbag deployment. Three cases of injuries in vehicle operators associated with airbag module covers are reviewed and discussed. Injuries ranged from the traumatic avulsion of a thumb to the development of a subdural hematoma with associated cerebral edema and respiratory arrest. Motor vehicle operators should be aware that although airbags can significantly reduce the severity of injuries sustained in frontal collisions the module cover has the potential to inflict serious, even fatal injuries.
